<p><strong>NOTES</strong>:</p>
<ul>
<li>
<p>iRedAdmin-Pro doesn't work with Active Directory, so if you choose to
authenticate mail users against Active Directory, you have to manage mail
accounts with Active Directory management tools.</p>
</li>
<li>
<p>This tutorial has been verified on Windows Server 2000, 2003, 2008, 2012,
2016, 2019, if you tested it on other versions and works well, please let us
know. <a href="https://www.iredmail.org/contact.html">Contact us</a></p>
</li>
</ul>
<h2 id="summary">Summary</h2>
<p>With Active Directory (AD) integration, you can get below features:</p>
<ul>
<li>User authentication against Windows Active Directory. You can now manage mail
user accounts, mail lists with AD.</li>
<li>Mail list support with group in AD.</li>
<li>Global LDAP Address Book with AD in Roundcube Webmail.</li>
<li>Account status support. Disable user in AD will cause this account disabled
in iRedMail.</li>
</ul>
<p>Since AD uses different LDAP schema, you will lose some iRedMail special features. e.g.</p>
<ul>
<li>Per-user, per-domain service control with LDAP (e.g. enable/disable
POP3/IMAP/SMTP services).</li>
<li>Advanced mail polices implemented by iRedAPD which relies on iRedMail
LDAP scheme.</li>
</ul>
<h2 id="requirements">Requirements</h2>
<p>To integrate Microsoft Active Directory with iRedMail, you should have:</p>
<ul>
<li>A working Linux/BSD server with iRedMail (OpenLDAP backend) installed.</li>
<li>
<p>A working Microsoft Windows (2000/2003) server, with Active Directory
installed and working properly, listen on port <code>389</code> (ldap://) or <code>636</code>
(ldaps://), and allow LDAP connections from iRedMail server.</p>
<ul>
<li>
<p>If you need to enable LDAP over SSL, please read
<a href="https://support.microsoft.com/en-us/help/321051/how-to-enable-ldap-over-ssl-with-a-third-party-certification-authority">this tutorial</a>.</p>
</li>
<li>
<p>If connecting to <code>389</code> doesn't work, try port <code>3268</code> instead.</p>
</li>
</ul>
</li>
</ul>
<h2 id="install-iredmail">Install iRedMail</h2>
<p>Please follow <a href="./index.html">iRedMail installaion guides</a>
to install iRedMail on Linux/BSD with OpenLDAP backend first, we will
achieve this AD integration by simply modifying some configure files.</p>
<h2 id="integrate-microsoft-active-directory-with-postfix">Integrate Microsoft Active Directory with Postfix</h2>
<p>We assume:</p>
<ul>
<li>
<p>Hostname of your AD server is <code>ad.example.com</code>, listen on port <code>389</code>. And it's
accessible from iRedMail server.</p>
<ul>
<li>We will use this hostname below, you can replace it by IP address of this
AD server if you want.</li>
<li>If you want to force LDAP connection with LDAPS, use port <code>636</code> instead.</li>
</ul>
</li>
<li>
<p>Base dn in AD is <code>dc=example,dc=com</code>, email addresses of all users end with
<code>@example.com</code> (Your mail domain is <code>example.com</code>).</p>
</li>
<li>All user accounts and mail list accounts are placed under dn
<code>cn=Users,dc=example,dc=com</code>. <strong>Note:</strong> LDAP dn is case-insensitive.</li>
<li>For ldap connection, protocol version <code>3</code> is recommended.</li>
<li>
<p>Store all mails on Linux/BSD servers, not on AD server.</p>
<ul>
<li>Storage directory is <code>/var/vmail/vmail1</code>, same as default in iRedMail.</li>
<li>Mailbox of user <code>support@example.com</code> will be
<code>/var/vmail/vmail1/example.com/support/Maildir/</code> (Maildir format).</li>
</ul>
</li>
</ul>
<h3 id="create-user-account-in-ad-used-for-ldap-query">Create user account in AD, used for LDAP query</h3>
<p>With iRedMail (OpenLDAP backend), we have a low-privileged account
<code>cn=vmail,dc=xxx,dc=xxx</code> with read-only privilege. And we suggest you create a
same account <code>vmail</code> in AD, with strong and complex password.</p>
<p><strong>NOTES</strong>:</p>
<ul>
<li>Dovecot treats characters as comment after a inline <code>#</code>, please don't use
<code>#</code> in password.</li>
<li>Seems Windows Server 2019 doesn't like user id without domain part by
default, please create the <code>vmail</code> user with your domain name instead. for
example, <code>vmail@domain.com</code> (replace <code>domain.com</code> by your real domain name).</li>
</ul>
<p>Make sure this newly created user is able to connect to AD server with
below command on iRedMail server:</p>
<pre><code class="language-shell"># ldapsearch -x -h ad.example.com -D 'vmail' -W -b 'cn=users,dc=example,dc=com'
Enter password: password_of_vmail
</code></pre>
<p>If it prints all users stored in AD server, then it's working as expected.</p>
<p>If you're using LDAPS, replace <code>-h ad.example.com</code> by
<code>-H ldaps://ad.example.com:636</code> instead:</p>
<pre><code class="language-shell"># ldapsearch -x -H ldaps://ad.example.com:636 -D 'vmail' -W -b 'cn=users,dc=example,dc=com'
Enter password: password_of_vmail
</code></pre>
<p>If LDAPS doesn't work, you may need to update parameter <code>TLS_CACERT</code> in
<code>/etc/openldap/ldap.conf</code> (RHEL/CentOS) or <code>/etc/ldap/ldap.conf</code> to use correct CA
certificate. For example:</p>
<ul>
<li>on CentOS: use <code>/etc/pki/tls/certs/ca-bundle.trust.crt</code>:</li>
</ul>
<pre><code>TLS_CACERT /etc/pki/tls/certs/ca-bundle.trust.crt
</code></pre>
<ul>
<li>on Debian/Ubuntu, use <code>/etc/ssl/certs/ca-certificates.crt</code>:</li>
</ul>
<pre><code>TLS_CACERT /etc/ssl/certs/ca-certificates.crt
</code></pre>
<h3 id="enable-ldap-query-with-ad-in-postfix">Enable LDAP query with AD in Postfix</h3>
<p>Disable unused iRedMail special settings:</p>
<pre><code class="language-shell">postconf -e virtual_alias_maps=''
postconf -e sender_bcc_maps=''
postconf -e recipient_bcc_maps=''
postconf -e relay_domains=''
postconf -e relay_recipient_maps=''
postconf -e sender_dependent_relayhost_maps=''
</code></pre>
<p>Add your mail domain name in <code>smtpd_sasl_local_domain</code> and <code>virtual_mailbox_domains</code>:</p>
<pre><code class="language-shell">postconf -e smtpd_sasl_local_domain='example.com'
postconf -e virtual_mailbox_domains='example.com'
</code></pre>
<p>Change transport maps setting:</p>
<pre><code>postconf -e transport_maps='hash:/etc/postfix/transport'
</code></pre>
<p>Enable AD query. <strong>Note</strong>: We will create these 3 files later.</p>
<ul>
<li>Verify SMTP senders</li>
</ul>
<pre><code class="language-shell">postconf -e smtpd_sender_login_maps='proxy:ldap:/etc/postfix/ad_sender_login_maps.cf'

</code></pre>
<ul>
<li>Create/edit file: <code>/etc/postfix/transport</code>.</li>
</ul>
<pre><code>example.com dovecot
</code></pre>
<p><strong>Note</strong>: the name <code>dovecot</code> used here is a Postfix transport defined in
<code>/etc/postfix/master.cf</code>, used to deliver received emails to local user mailboxes.</p>
<p>Run <code>postmap</code> so that postfix can read it:</p>
<pre><code># postmap hash:/etc/postfix/transport

<p><strong>Notes</strong>:</p>
<ul>
<li>If your user have email address in both <code>mail</code> and <code>userPrincipalName</code>, you
will get duplicate result. Comment out <code>leaf_result_attribute</code> line will fix it.</li>
<li>If your mail group account doesn't contain attribute <code>mail</code> and
<code>userPrincipalName</code>, please try <code>query_filter = (&amp;(objectClass=group)(sAMAccountName=%u))</code> instead.</li>
</ul>
<p>Also, we need to remove iRedAPD related settings in Postfix:</p>
<ol>
<li>Open Postfix config file <code>/etc/postfix/main.cf</code></li>
<li>Remove setting <code>check_policy_service inet:127.0.0.1:7777</code>.</li>
</ol>
<h3 id="verify-ldap-query-with-ad-in-postfix">Verify LDAP query with AD in Postfix</h3>
<p>We can now use command line tool <code>postmap</code> to verify AD integration in postfix.
Before testing, we have to create two testing mail accounts first:</p>
<ol>
<li>Create a mail user in AD. e.g. <code>user@example.com</code>.</li>
<li>Create a mail group in AD. e.g. <code>testgroup@example.com</code>, then assign mail
user <code>user@example.com</code> as group member.</li>
<li>Query mail user account with below command:</li>
</ol>
<pre><code class="language-shell"># postmap -q user@example.com ldap:/etc/postfix/ad_virtual_mailbox_maps.cf
example.com/user/Maildir/
</code></pre>
<p>If nothing returned by the command, it means LDAP query doesn't get expected
result. Please set <code>debuglevel = 1</code> file <code>/etc/postfix/ad_virtual_mailbox_maps.cf</code>,
then query again, it now will print detailed debug message. If you're not
familiar with LDAP related info, please post the debug message in our
<a href="https://forum.iredmail.org/">online support forum</a> to get help.</p>
<p>Verify sender login check:</p>
<pre><code># postmap -q user@example.com ldap:/etc/postfix/ad_sender_login_maps.cf
user@example.com
</code></pre>
<p>Verify mail group</p>
<pre><code># postmap -q testgroup@example.com ldap:/etc/postfix/ad_virtual_group_maps.cf
user@example.com
</code></pre>
<p><strong>NOTE</strong>: <code>postmap</code> return nothing if:</p>
<ol>
<li>mail group doesn't exist</li>
<li>mail group doesn't have any members</li>
</ol>
<h3 id="remove-iredapd-integration-in-postfix">Remove iRedAPD integration in Postfix</h3>
<p>iRedAPD relies on iRedMail LDAP scheme, so it's useless if you integrate
iRedMail with Active Directory. We should remove the integration in Postfix
to save some system resource.</p>
<p>To disable iRedAPD, please read tutorial: <a href="./manage.iredapd.html">Manage iRedAPD</a>.</p>
<h2 id="enable-active-directory-integration-in-dovecot">Enable Active Directory integration in Dovecot</h2>
<p>To query AD instead of local LDAP server, we have to modify Dovecot config file
<code>/etc/dovecot/dovecot-ldap.conf</code> like below:</p>
<div class="admonition attention">
<p class="admonition-title">Attention</p>
<p>If you use LDAPS and <code>hosts =</code> doesn't work, please replace it by <code>uris =</code>
instead. Check
<a href="https://doc.dovecot.org/configuration_manual/authentication/ldap/">Dovecot tutorial</a>
for more details.</p>
</div>
<pre><code>hosts = ad.example.com:389
ldap_version = 3
auth_bind = yes
dn = vmail
dnpass = passwd_of_vmail
base = cn=users,dc=example,dc=com
scope = subtree
deref = never
# Below two are required by command 'doveadm mailbox ...'
iterate_attrs = userPrincipalName=user
iterate_filter = (&amp;(userPrincipalName=*)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))
user_filter = (&amp;(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))
pass_filter = (&amp;(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))
pass_attrs = userPassword=password
default_pass_scheme = CRYPT
user_attrs = =home=/var/vmail/vmail1/%Ld/%Ln/,=mail=maildir:~/Maildir/
</code></pre>
<p>Restart dovecot service to make it work.</p>
<div class="admonition attention">
<p class="admonition-title">Attention</p>
<p>We don't have per-user quota limit here, you can set a hard-coded
quota for all users in <code>/etc/dovecot/dovecot.conf</code>. For example:</p>
<pre><code>plugin {
[... omit other settings here ...]
# Format: integer number + M/G/T (M -&gt; MB, G -&gt; GB, T -&gt; TB).
quota_rule = *:storage=1G
}
</code></pre>
<p>You can also modify the <code>user_attrs =</code> line to get per-user quota from a
LDAP attribute in AD. For example, query per-user quota limit from
attribute <code>postOfficeBox</code> which contain an integer number and treated as
number of gigabytes:</p>
<pre><code>user_attrs = =home=/var/vmail/vmail1/%Ld/%Ln/,=mail=maildir:~/Maildir/,postOfficeBox=quota_rule=*:storage=%{ldap:postOfficeBox}G
</code></pre>
<p>Note: This per-user quota will override the one hard-coded in dovecot.conf.</p>
</div>
<p>Now use command <code>telnet</code> to verify AD query after restarted Dovecot service:</p>
<pre><code># telnet localhost 143 # &lt;- Type this
* OK [...] Dovecot ready.
. login user@example.com password_of_user # &lt;- Type this. Do not miss the dot in the beginning
. OK [...] Logged in
^] # &lt;- Quit telnet with &quot;Ctrl+]&quot;, then type 'quit'.
</code></pre>
<p>Note: Do NOT miss the dot character before <code>login</code> command. if it returns
<code>Logged in</code>, then dovecot + AD works.</p>
